Before starting this step remove sddm or any login manager because it gives problems with wayland/hyprland

Following the Arch Linux PCI Passthrough Guide, we need to enable IOMMU and then check if it's enabled using the following code:

sudo dmesg | grep -i -e DMAR -e IOMMU

After this, we need to list and check where our PCI devices are mapped to IOMMU groups.

shopt -s nullglob
for g in $(find /sys/kernel/iommu_groups/* -maxdepth 0 -type d | sort -V); do
    echo "IOMMU Group ${g##*/}:"
    for d in $g/devices/*; do
        echo -e "\t$(lspci -nns ${d##*/})"
    done;
done;

In my case:

IOMMU Group 19:
    0a:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Navi 22 [Radeon RX 6700/6700 XT/6750 XT / 6800M/6850M XT] [1002:73df] (rev c1)
IOMMU Group 20:
    0a:00.1 Audio device [0403]: Advanced Micro Devices, Inc. [AMD/ATI] Navi 21/23 HDMI/DP Audio Controller [1002:ab28]

Now we have to isolate the GPU, but first, we need to load vfio-pci before the GPU drivers have a chance to bind to the card.

We have to edit the /boot/loader/entries/<id>.conf with the ids of pci we want to isolate:

options ... iommu=pt vfio-pci.ids=1002:73df,1002:ab28

We need to add vfio_pci, vfio, vfio_iommu_type1 to /etc/mkinitcpio.conf:

MODULES=(... vfio_pci vfio vfio_iommu_type1 ...)
BINARIES=(...)
FILES=(...)
HOOKS=(... modconf ...)

After this, we have to regenerate the initramfs with this command and reboot:

sudo mkinitcpio -P

Now we can check if if vfio-pci is loaded properly with this command:

lspci -nnk

0a:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Navi 22 [Radeon RX 6700/6700 XT/6750 XT / 6800M/6850M XT] [1002:73df] (rev c1)
